Determining The Age Of A Stabilized Dune Field, Carissa Raymond

UCARE Research Products

The aim of this project was to assess the development and age of the Kearney Dunefield in central Nebraska through the collection and analysis of sand samples from the inactive dunes. These dunes are not part of the well-known Nebraska Sandhills, and so far have not been thoroughly studied. Similar assessments have been conducted on dune fields throughout the Great Plains, and this study seeks to place the Kearney Dunes into a regional context.

The OSL ages for the Kearney cores fall between approximately 590 and 690 years ago. These dates overlap with a period of activation for the Nebraska …

Adiabatic Cooling And Warming, John J. Renton, Thomas Repine

Readings and Notes

In order to understand how deserts form one needs to understand two processes called adiabatic cooling and warming.

Coal Geology: The Origin Of Coal, John J. Renton, Thomas Repine

Readings and Notes

Coal forms from the tissues of plants with the major contributor being the woody tissues, cellulose and lignin, from trees growing in fresh-water wetlands. Land plants first evolved during the early Devonian and by the end of the period had adapted to most terrestrial environments. Beginning in early Pennsylvanian time, vast portions of the eastern portion of Laurentia were covered with coal-forming swamps and bogs, environments that were to be repeated throughout the remainder of the Paleozoic Era and again in the Jurassic, Cretaceous and Tertiary Periods. It was during these times that the combination of climatic conditions and wetland …

Coal Genesis, John J. Renton, Thomas Repine

Readings and Notes

Most textbooks classify coal as a sedimentary rock even though it does not fit the definition of a sedimentary rock. While a sedimentary rock is a "rock formed from the products of weathering and erosion", coal forms from the remains of land plants. In fact, coal doesn't even fit the definition of a rock. A rock is defined as "mixture of minerals" and minerals are defined as "natural occurring, solid, inorganic substances ..• " Coal is composed largely (􀀴90+%) of organic substances (macerals) which, by definition, are not minerals. If coal must be classified as a rock, because it forms …

Seismic Reflection Profiling Near Middletown, Ohio And Interpretation Of Precambrian Deformational Settings, David Joseph Peterman

Browse all Theses and Dissertations

The reprocessing of four vibroseis seismic reflection lines at the AK Steel facility in Middletown, Ohio, provides new insight on the age, deposition, and structural deformation of the pre-Mount Simon sedimentary sequence below Butler and Warren Counties. Processing was focused on the pre-Mt. Simon reflections to reveal gently west-southwest dipping reflectors that make a slight angular unconformity with the overlying Paleozoic sedimentary strata. This pre-Mount Simon sedimentary sequence has been encountered in several wells from western Ohio, Indiana, and northern Kentucky and has been identified as the Middle Run Formation. Examination of the weak and discontinuous seismic character of the …
